Devices able to identify radioactive isotopes by analyzing the characteristic gamma emission spectra.
The devices are often multipurpose/multitask instruments able to detect different forms of radiation and perform a variety of functions; used to search, detect and identify radioactive materials.

PM1401K-3 Multipurpose radiation detector and radionuclide identifier

PM1401K-3 is the smallest and the most lightweight instrument in the world able to operate simultaneously as a search instrument, asurvey meter, an alarm device, a surface contamination monitor, and a radionuclide identifier.

All radiation sensors are internally incorporated in the instrument's IP65 body. Data such as gamma spectra, doserate, etc are shown on a bright and easy-to-read colour LCD; a belt clip and automatic operation mode allow for hand-free operation, while the user goes about their normal tasks.

· Search for radioactive sources (PM1401K-3/3M/3E/3P):
The high sensitivity of the solid-state CsI sensor aloows search and localization of radiation sources with high efficiency, including hidden sources.

· Detection of neutron emitters (PM1401K-3/3E/3P):
A nuetron sensor (He3 - no export restrictions) is used to amplify the instrument's response to special nuclear materials (uranium and plutonuim isotopes)

· Measurement of Cs137 specific activity (PM1401K-3/3M/3P):
Specific activity (Bq/kg) of the radionuclide Cs-137 can be measured in food, water, and environmental samples.

PM1403 Multipurpose radiation detector and radionuclide identifier

The PM1403 is a multi-application instrument, based on a control unit with an internal CsI scintillation detector supplied with an optional range of external probes to greatly increase the funcionality of the instrument.

Data including radionuclide identification is shown on a large colour LCD screen; the device has an incorporated GPS module, and wireless communication by GSM protocol and Bluetooth. Visual and audible alarms alert the user to high radiation levels; optionally, the PM1403 can be supplied with a telescopic extension tube.

The PM1403 can be supplied with any combination of the external probe set.
